Title: Fluid damped bushing
Inventor: HEIN RICHARD D
IPC: F16F13/14
Filed: 1995-07-31
Abstract: A fluid damped bushing (10) comprising a metallic sleeve ( 12) and an annular elastomeric body (14) mold bonded to the exterior of the metallic sleeve.  The elastomeric body has a spaced apart pair of fluid containing recesses ( 16, 18) in its exterior surface with an intermediate recess (20) positioned between the fluid containing recesses.  An inertia track plate (22), which is formed from a relatively rigid material, is positioned within the intermediate recess, and the track plate has a flow passage (24) formed in its exterior surface, opposed ends of the flow passage being in fluid communication with the fluid containing recesses.  The bushing is circumscribed by longitudinally short, metallic rings (26, 28) on longitudinally opposed sides of the recesses, and is then tightly surrounded by a metallic sleeve (30) which has an elastomeric inner liner (32) mold bonded to its interior surface.  The elastomeric body also has a second intermediate recess (34), which is like the intermediate recess (20) and which is diametrically opposed thereto, and the second intermediate recess is also fitted with a track plate (36).  The track plate (36) is like the inertia track plate (22), except that the track plate is not provided with a flow passage corresponding to the flow passage (24).

Title: Venting device
Inventor: CARR ANTHONY HUGH
IPC: C12M1/24
Filed: 1994-02-09
Abstract: A venting device for a culture bottle hav-ing a seal incorporating a septum comprising an outer sleeve (702) in which a guide tube (704) is axially slidable and a needle carrier (706) which is axially slidable in the guide tube. The complete device is a sterile package sealed by a foil (712) at the forward end of the outer sleeve. In operation, the guide tube first moves to cut and deflect the foil, and the needle carrier then moves to cause the needle to penetrate the bot-tle septum. Asepticity is maintained substan-tially up to the moment of septum penetration by virtue of use of the guide tube for cutting and deflecting the foil out of the path of the needle.

Patent CA-2168053-A1 (CA)
Title: Packer inflation system
Inventor: CORONADO MARTIN P
IPC: E21B33/127
Filed: 1996-01-25
Abstract: An inflation tool for an external casing packer (ECP) is provided. It allows isolation of each ECP and inflation with mud, cement, or other fluids. The opening for the ECP is isolated by appropriate seals, while a passage in the inflation tool is closed off by a plug which allows internal fluid pressure build-up. A  sliding sleeve valve is responsive to built-up pressure and opens to allow access to the ECP. Upon complete inflation of the ECP, the pressure applied is removed, allowing the sleeve to close and the pressure between the seals surrounding the opening to the ECP is equalized with the wellbore. Excess mud or other inflation material can be reversed out by a bypass feature around the plug. A pressure-relief feature in the inflation tool allows further pressure equalization for the string, which was used to run the tool in the hole, to facilitate its removal.

Title: Method of and apparatus for controlling modulation of digital signals in frequency-modulated transmissions
Inventor: KOENCK STEVEN E
IPC: G06K7/10
Filed: 1995-03-03
Abstract: A programmable apparatus for generating a frequency modulated signal at a selected center frequency in accordance with digital data with at least first and second data levels. A modulator (331) is responsive to an input modulation signal for generating the frequency modulated signal at a frequency dependent on a quiescent voltage appearing at its input. A circuit (380) is provided for sampling and storing a value of the quiescent voltage. An addressable memory (301) stores a plurality of offsets. A programmable adding circuit (345) adds a downloaded offset voltage to the stored value of the quiescent voltage to output a high modulation voltage. A programmable subtracting circuit (349) subtracts a downloaded offset voltage from the stored value of the quiescent voltage to provide a low modulation voltage. An addressing circuit addresses the memory in accordance with a data transmission parameter for downloading a corresponding offset to the adding and subtracting circuits. A switch or multiplexor (346) is coupled to the subtracting and adding circuits for generating and applying to the modulator input an input modulation signal.

IPC: H04B17/00
Filed: 1996-03-08
Abstract: A method and apparatus for measuring a characteristic of a fading signal received using two or more branch diversity receivers (100) is presented. This fading characteristic is proportional to the speed of the user. In a first embodiment the number of times the antenna branches change in a selection diversity process is counted (160), and the result is scaled (170) for imbalance between the branches. The output of a fading quality estimator (180), indicative of the fading and generally proportional to the speed, is thereby obtained.

Patent CA-2198101-A1 (CA)
Inventor: SHENK EDWIN K
IPC: H04N1/06
Filed: 1995-08-31
Abstract: L'invention concerne un procédé et un dispositif servant à générer un signal d'horloge de sortie régulée (PCLK), dont la phase et la fréquence se réfèrent à celles d'un signal d'entrée. La compensation est programmable, afin de permettre à une source extérieure, telle qu'un processeur, de transférer un facteur de compensation, de manière à créer une boucle à phase asservie à fréquence variable. Un diviseur séparé programmable (78') est transféré avec une valeur complémentaire, afin de régler le signal de fréquence variable sur la fréquence du signal d'entrée alimentant la boucle à phase asservie. Ceci permet à la boucle à phase asservie de varier sur une plage importante de fréquences sans qu'il soit nécessaire de régler l'oscillateur asservi (66') et le filtre de boucle (64'). Ce procédé et cette boucle à phase asservie permettent particulièrement de produire des horloges de pixels sélectionnées dans un système d'imprimante informatique.
